by News Staff / July 14, 2014

The Happiness Blanket was tested on a group of volunteers aboard a recent British Airways flight from Heathrow to New York as part of a study on how to reduce jet lag. A headband worn by each passenger detects relaxation levels and the blankets indicate mood by changing color – red means alert or anxious, and blue means relaxed.
